3. Připojte napájecí zdroj: Connect the AC 80-260V power supply to the meter's input terminals as shown in the wiring diagram. Ensure correct polarity if applicable, though for AC, line and neutral are typically interchangeable for the meter's power input.
4. Instalace proudového transformátoru (CT):
   • Identify the load wire (live wire) of the circuit you wish to monitor.
   • Open the CT clamp and pass only the load wire through the center hole of the CT. Ensure the arrow on the CT points in the direction of current flow (from source to load).
   • Connect the two wires from the CT clamp to the CT input terminals on the meter.
5. Ověřte připojení: Double-check all wiring connections against the diagram to ensure they are secure and correct.
6. Obnovit napájení: Once all connections are verified, restore power to the circuit. The meter display should light up.

6. Návod k obsluze

The meter is designed for straightforward operation. Once powered on, it will immediately begin displaying real-time measurements.

6.1. Ovládání podsvícení

To control the display backlight:

• Zapnout/Vypnout: Briefly press the button located on the front panel. Each press will toggle the backlight state.
• Úspora dat: The meter automatically saves measurement data regardless of the backlight status.

6.2. Overload Alarm Setting

To set or adjust the current overload alarm threshold:

1. Vstupte do režimu nastavení: Press and hold the button for approximately 3 seconds until the current alarm threshold value starts flashing on the display.
